:heavy_check_mark: List and Filter Configured Scheduled Tasks

:heavy_check_mark: List and Describe Autoscaling

:heavy_check_mark: Update Autoscaling Configuration

:heavy_check_mark: Describe Scheduled Tasks for Specific ElasticGroup

:heavy_check_mark: Configure Scheduled Tasks for Specific ElasticGroup

:heavy_check_mark: Check Instances health

## Installation:
#### First:
You need to configure SpotInst Credentials.you can configure the credentials by creating a file ~/.spotinst/credentials and add a profile

Example

export account_id="act-xxxxx"
```
#### Second:
Install the Package
```bash
pip3 install elasticgroup-cli
```

elasticgroup-cli --instances-health <Elasticgroup-Name>
```
List configured Autoscaling Actions of specific Elasticgroup
```bash
elasticgroup-cli --describe-autoscaling <Elasticgroup-Name>
```
Configure Autoscaling for specific Elasticgroup
```bash
elasticgroup-cli --configure-autoscaling <Elasticgroup-Name> --min=x --max=x --target=x
```

List configured Scheduled Tasks of specific Elasticgroup
